cut a hole in the middle of a large foam battery block roughly the same size as 1/4 weight. You should be able to stack them in that hole and then just wrap some electrical tape around the foam to hold it in place. This will add 3 oz in the middle of the battery foam.

I'm considering making another one for the front of the battery since all I own at the moment are shorty packs.

how well does the shorty work in the sc10? I didnt think people ran them.

+1

no clue. Never raced my SC10 LOL.

I just finished it recently and haven't had a chance to run it yet. I will eventually grab a full size pack, but for now, I think I will just add weight to the battery tray in front of the battery. It will basically give the same result. I just have to figure out how much to add.... I figure around 100 grams will work, which is 3 1/2 oz. so I'll prolly just do another 3 oz block

Hated it. You can try and add weight but that will be a PITA to get figured out. Run a stick and don't worry about it.

so without a cut foam I should put batt. in front and then put the full block of foam behind it with 3oz inside the foam?

ok, you still run the same foam as before..... usually a nice large block in the rear of the battery tray. Put the hole in that piece of foam and add the weight. I suggest you get a second foam and do it on that one so that way if you don't like the effect it has, you can swap back to no weight.

In my case, I am going to add another weighted foam with 3 oz in front of the battery to make up the difference in weight of the shorty pack. It's not exact, but it will be close enough.

so if the front of your truck is --->

[foam with weight] Battery [foam with no weight]

If you still don't understand, i'll take a few pics when I get home tonight.

To add or remove weight
 

I have been tossing around the idea of using a shortty pack. i thought it would be beneficial to reduce the over all weight of my SC10. It seems to me that a lighter turck would be faster. I don't understand the concept of added a bunch of weight to my truck.

When I raced back in the late 80's, early 90's you did everything you could to reduce the weight of your buggy and stadium truck(no SC vehicles back then). Can someone help me with my inability to understand adding weight.

Two points to make about the weight:
1. Its not about just adding weight but adding weight where its needed. That's why the ballast weight is such a nice tuning option. You put the weight directly where its transfer during cornering/deceleration/acceleration has the most effect.
2. We have almost limitless power now with modern motor and lipo technology. Back in the day you set up your vehicle to run 4 minutes and a handful of seconds and then the battery dumped. Now you can run for 15-20 minutes (if you wanna cook your motor).
These things being said, my SC10 has absolutely no weight in it and I really like it. It feels more responsive than my sons SC10 with the ballast weight and the rear end doesn't over-swing when you get it to rotate in corners. Its all personal preference.

Compare what we have today with what we had 10-20 years ago. Back then it was hard to build a complete buggy and keep it at or under the 52 ounce ROAR rule. The Lipo battery has changed that big time!

Cueball, you are correct- theoretically lighter is faster.

BDS81175- Funny you mentioned your sons truck likes to over-swing with weight added. I'm assuming it's added to the rear. My SC10 did the same thing when biasing more weight to the rear. Now I just play with battery placement.

Less weight is faster...regardless of better motors and better batteries with ability to power more weight....you all need to remember that when cornering your tires still need to carry that additional load as well. Mechanical downforce (weight) has a detrimental effect on any vehicle when cornering. First thing any race car should get is a weight reduction, it's the most effective "upgrade" you can do to a car after tires.

Yes it's used to balance a chassis but that's all it should be used for.

I use a shorty in my SC10 and like it. I can't drive worth a crap but it's fast as hell. Run 17.5 blinky class and had a guy grab my truck and tech it after a qualifier because its flippin fast down the straights using a Revtech with the timing actually turned back on the motor and temps well under 145 after a run. (granted they don't weigh us nor require it)

I'd kinda have to agree with VegasHB, for me at least. I like the feel of a nimble vehicle whenever there is decent traction by a long shot. My T4 has weight all over it (1/2 oz in front of receiver, 1/4 in the rear triangles, + the ballast weight) and it doesn't handle nearly as well on our local tracks (medium to high bite dirt/clay) as my SC10. I'm gonna give my T4 one more shot setup like it is. If it doesn't work, I'm stripping the weight and setting it up like my SC10.

You have a point, but I will have to disagree. With out enough weight your tires will not get sufficient traction whether it be forward, aft or side to side.

Ditto. That's why I have seven 1/2oz weights behind the battery! The SC10 washes out too much.

Regarding the SC10B, any of you guys planning on converting yours to it? I might just get the body kit and the tires and wheels for a "buggy" feel...

:smile:

Funny about the weight talk...I've been running 2.5 oz behind the battery and .75 on the servo forever, and it handles fine...but I keep telling myself to take it off and see what she'll do.
